received status code 204 (no content)

I am using Apollo client with react in the front end running on port 3001. In the back end I am running node/express on port 3000.

In the front end, I have a nav bar that is supposed to run a query and get the user data. When I look at the chrome devtools / network I see something like this:

I am not sure why there is a fetch & json at the same time and why the fetch is coming back with response of 204 (empty content). Shouldn’t I only get a fetch with 200 and no json request.

Here is my config in the front end:

const networkInterface = createNetworkInterface({
  uri: '//localhost:3000/graphql'   // pointing to the backend server at port 3000
});

networkInterface.use([{
  applyMiddleware(req, next) {
    if (!req.options.headers) {
      req.options.headers = {};  // Create the header object if needed.
    }
    // get the authentication token from local storage if it exists
    const token = localStorage.getItem('token');
    req.options.headers.authorization = token ? `Bearer ${token}` : '';
    next();
  }
}]);

const client = new ApolloClient({
	dataIdFromObject: o => o.id,
	networkInterface
});

const reducers = combineReducers({
	apollo: client.reducer()
});

const store = createStore(
  reducers,
  composeWithDevTools(applyMiddleware(client.middleware()))
);

Here is my code for the navbar:

const query = gql`
	query {
		user {
			id
			email
		}
	}
`;
export default connect(null, actions)(graphql(query)(NavBar));

And here are snippets code at the backend server:

app.use('/graphql', expressGraphQL({
	schema,
	graphiql: true
}));

Here is the queryType in the backend. I am returning an object just for testing. I tried to wrap the object with Promise but I get the same result.

const RootQueryType = new GraphQLObjectType({
	name: 'RootQueryType',
	fields: {
		user: {
			 type: UserType,
			 resolve(parentValue, args, req) {
				 return {id: "234324", email: "[e-mail]"}; 
			 }
		}
	}
});

When I try the query in graphiql, things seems to work fine.

Could you please help me figure this out. Thanks
